🌱 How to Care for Inch Plant to Prevent Leaf Spot?

💧 How to Water

Water approximately every 7 days, or when the top inch of soil feels dry. Always allow excess water to drain fully — overwatering is the most common problem with this genus. Use filtered or room-temperature water when possible.

☀️ Lighting

Place near an east or west-facing window for bright, indirect light. At least 6 hours of indirect light daily promotes lush, compact growth. Avoid intense direct sun that can scorch the foliage; equally, too little light causes leggy, pale stems.

🪴 Ideal Soil

Use a well-draining mix: 60% potting soil with 40% perlite works well. Ideal pH is 5.0–6.5 (slightly acidic). Repot annually or when roots start emerging from the drainage holes.
